Hastings Update — Trip Elmore & Mike Burton (Dore & Whittier). Donna DiNisco (DiNisco Design (See Attached) 2. LCP/Pelham Road Update — Donna DiNisco & Rick Rice (DiNisco Design) Donna discussed a slide presentation that showed the Existing Site Plan, Two Site Plan Options and LCP Master Plan Recommendations. • The Existing Plan confirmed wetlands and vernal pool locations with setbacks of 50' and 100' feet. It also showed ledge, existing detention basin, and a steep slope from Pelham Road. • Option Awas dismissed due to LCP location, LCC expanded parking was undesirable and expansion opportunities were lacking. • Option B provided a preferred location for LCP and expanded parking. LCC showed better expansion opportunities. LCC expansion could possibly have a playground that could be shared with LCP. It was stated a VRF, (Variable Refrigerant Flow), system would be used for LCP. Two LCP Master Plan Options were shown. One option relocates LCC parking, provides for an LCC expansion location and moderate ledge removal. The second option did not displace LCC parking, major ledge removal and provides and an LCC expansion location. Timeline was discussed. It was stated that for the fall Town Meeting, LCP would likely be bundled with the Hasting's School Project and Fire Station Project. The LCC expansion would be further evaluated as a future work. PBC asked about access restrictions by the Scottish Rite if any. DPF stated the Scottish Rite were favorable with parking next to them, but asked about exiting via Marrett Road. PBC asked if we have clear knowledge of what LCC's needs are. Designers confirmed. DPF stated we will move forward on the LCP with consideration for LCC expansion. Historic restrictions limit where building(s) can be placed. There will be a meeting with the Historical Society on how they view restrictions. The Carriage House could be moved, but would need to stay on site. It was commented on the importance of safe pedestrian traffic with lots of children traveling between LCP and LCC. 3. Clarke/Diamond Update — Ryan DiRico, Mike Dumaresg, Jerry Hammersley, Mike Lambert, Alan Steinberg (BOND), Paul (HILL) & Ken DiNisco (DiNisco Designs) With many of the project's work still needing to be completed, BOND representatives provided the Clake/Diamond updates. Diamond Update — Jerry Hammersley of BOND MEP subs working on getting equipment on-line getting ready for the Commissioning Agent. Classroom wing finishes are done, waxing floors tomorrow, railings in stairwells are getting done and we are in good shape all around on the addition. Jerry discussed the work that still needs to be finished up in various areas. This includes electrical, drywall, ceiling tiles, floors, kitchen, overhead HVAC piping and chill beams. Cleaners are coming in on 2nd shift when trades are not there. Ken stated that all school equipment needs to be in place by Monday 7/31. Floors need to be waxed and furniture in place ready for teachers August 21 st. All inspections to date have been done. Lots of finish work still needs to be done. Canopy over main entrance still needs to be closed in. Bond stated the Fire Alarm is live now. Site work is in good shape and a little under halfway done completing 400'-600' feet of curbing a day. Phasing plan to have guys start to work on formwork and rebar to get sidewalks done. Landscaping actively on site. Marbardy is placing loam as he moves along, and will be ready to spread once sidewalks are completed. Bond stated subs are working long shifts averaging 110 workers on site. The rest of the doors and frames have been delivered. Bond stated unforeseen issues with conflicts above the ceilings caused some delays but all issues appear to be resolved. PBC asked what the big worries are. It was stated the boiler room with hot water will go on-line in September but not for the start of school. DPF stated the commissioning is going well, but concerns are a Sept/Oct. final commissioning. Ken commented the big issue with commissioning is indoor air quality. And documentation needed Certificate of Occupancy. PBC asked if this information has been conveyed to the School Department and Superintendent. Yes. PBC Meeting 07.26.17 Question asked about work after start of school. Work will continue in closed off corridor on 2nd floor during the school day, and second shift for punch list.

D&W update on MSBA Process and CA transition team The project team met with the MSBA on Thursday July 20th to review the Schematic Design submission and answer any open question that may exist. There were few comments on either the submission binder or financial worksheets supplied. They confirmed that the MSBA would be participating in the project with a 35.79% reimbursement rate on MSBA REIMBURSABLE costs, which equates to a Maximum Total Facilities Grant of $16,492,249.00. In the meeting a brief review of SD comments, legal responsibilities of the district and limitations by the MSBA, and acknowledgement that this was the point of transition from the Feasibility and Schematic Design stage and moves the project into the hands of the MSBA Construction Administration team, which is Michael McGurl. The MSBA asked if there were any changes to the design or OPM teams. DiNisco stated that they were changing the Electrical Engineer for the project and D&WMP stated that we were going transition to our Construction Project Director as was presented in our proposal and interview. Mike Burton will replace Trip Elmore as the Project Director. The MSBA asked that we revise our Organization Chart and forward the new one. 1ANA(;t?NIENT 1',AI I'NERS, 1,I,(' MSBA Transition Meeting: The MSBA discussed a brief review the Module 6 (Design Development) process and acknowledged that the district was proceeding prior to Board and Local approvals, so reimbursement would not take place until both of those milestones take place. They stated that they will want to do a design drawing PROJECT MANAGERS review meeting at some point in the fall in the Designers office.

D&W update on Walsh Brothers At Schematic Design there were issues getting aligned with large budget variances between the Designers estimate and Walsh Brothers estimate which became a concern by the project team. Recently that concern was raised to Walsh Brothers to determine if this was a viable path forward with them on the team There was a meeting on the 20th at DiNisco's office where the issues were openly discussed and the team is confident that we can work together to solve the earlier issues in the next Design Development phase. The team agreed that we are moving into DD with Walsh Brothers. 3. DiNisco update on Green Engineer and Traditional Energy The PBC was forwarded a copy of the Green Engineers latest report which focused on evaluating the building Geothermal system and the overall energy consumption and cost compared to a traditional natural gas boiler and chiller system. The conclusion of this report indicates that the Geothermal system consumes more energy at todays' current electrical and natural gas rates, is not forecasted to result in any payback for the useful life of the building, and has an increased cost of more than $2 Million. With this new information, the PBC discussed many other beneficial uses for that level of "sustainable energy' investment in other places that actually have a positive impact on sustainable energy use. The PBC recommended that this report be circulated to the Lexington policy makers, School Committee and the Sustainable Lexington Committee for their review and action. It was noted that Geothermal decision has been made by the Lexington policy makers and they would need to change that decision for the project to proceed with conventional heating and cooling. The Designer was asked if there was time to switch HVAC generating systems and stay on schedule, to which they stated that the decision would need to be made in the next 2 or 3 weeks to stay on track. The Chair stated that the PBC had asked for this evaluation from the Designers' consultant, the Green Engineer. This report from the Green Engineer does not support the use of a Geothermal system and therefore the town has reason to review this information again. The PBC asked the Public Facilities Department to forward this report to the Sustainable Lexington Committee for their comments, and then to the Lexington policy makers and School Committee for their reaction to this new information which potentially could be a decision to eliminate the Geothermal system from the project. The PBC stressed that this review must be conducted quickly as after 3 weeks there could be schedule impacts to the design and project schedule. Several other PBC discussions focused on the impact of changing systems in terms of space in the building for NG boilers, roof space for equipment, schedule impacts in construction which would be explored in depth upon receiving a different direction form the Town. 4.
